No, I haven't heard about those freqs.or the band. The URL you sent me
didn't work I wonder if it also does AM, FM, or SSB since you said PEP.
I'll run this by Tom, perhaps he knows. Lemme know.

- Subject: Re: New M.U.R.S. Unlicensed VHF Radio Service starts
The section below that I find most interesting is 95.1303(b),where
operation aboard an aircraft is prohibited. I am the crew chief,and a
student pilot,for a hot air balloon crew here in the Phoenix,area. I
know of at least 5 crews,only 2 of whom I have found licenses
for,that use at least 4 frequencies in this range,(151.625 MHz,
151.805 MHz,151.895 MHz,and 151.955 MHz),for their air-ground
communications. (We still use 27 Mhz.) It isn't going to be long
before other balloonists around the country find out about MURS,and
start using these radios for the same purpose. And since some of the
crews are using mobile radios in their chase vehicles,with 5/8 wave
whips, it's almost guaranteed that they aren't operating at 2 watts
I wonder how (if.....) the FCC is going to enforce the provisions of
the rules that prohibit this type of use? The users are already
there. Just because I haven't found any balloon crews who were
already using the frequencies that are now assigned to MURS, doesn't
mean there aren't any,either here in the Phoenix area,or elsewhere.
It's going to be interesting to watch these channels around the
launch site on the weekends. I wonder how long it'll take for crews
to start showing up on these channels?
Sincerly,John H. Guetherman
(I did some monitoring. 154.600 is definately being used by a local
balloon crew. I think 154.570 is also,but they weren't quite within
range to hear clearly. I actually saw the chase crew using the
radio,while hearing her on 154.600.)

2 W effective radiated power (ERP).
95.649 Power capability
No CB, R/C, LPRS, FRS, MICS, MURS or WMTS unit shall incorporate
provisions for increasing its transmitter power to any level in
excess of the limits specified in 95.639.
95.651 Crystal control required
All transmitters used in the Personal Radio Services must be crystal
controlled, except an R/C station that transmits in the 26-27 MHz
frequency band, a FRS unit, a LPRS unit, a MURS unit, a MICS
transmitter, or a WMTS unit.
95.1303 Authorized locations.
(a) MURS operation is authorized:
(b) MURS operation is not authorized aboard aircraft in flight.
95.1309 Channel use policy.
(a) The channels authorized to MURS systems by this part are
available on a shared basis only and will not be assigned for the
exclusive use of any entity.
(b) Those using MURS transmitters must cooperate in the selection
and use of channels in order to reduce interference and make the most
effective use of authorized facilities. Channels must be selected in
an effort to avoid interference to other MURS transmissions.
- Listen for WalMart on 154.570 and 154.600.
Wendy's at Metro Center uses 154.570 for the drive-thru window.
Banyantree Apartments near Cactus and I-17 uses 154.570.
And, some school uses 154.600 near Cactus and I-17.
Castles N Coasters at Metro Center has BPR40 two-way VHF radios, and sometimes use the 154.570/154.600 MURS, and also 151.625.
